REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 309,661, dated December 23, 1884.

Application filed May 1:3, 1884. (No model.)

To all whom it may concern:

Be it known that we, JOHN STERN and VILLIAM MEYN, of Detroit, in the county of Vayne and State of Michigan, have invented new and useful Improvements in Refrigerators; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this speciiication.

This invention relates to certain new and useful improvements in the construction of refrigerators; and the invention consists in the peculiar construction of a cut-off leaf or damper for closing the air-passages between the ice-receptacle and the cooling-chamber, all as more fully hereinafter set forth.

Figure l is a perspective view, partly broken away, showing interior. Fig. 2 is a similar view with the lid open and damper closed. Fig. 3 is a longitudinal vertical section.

In the accompanying drawings, which form a part of this speciiication, A represents a refrigerator-box,provided with the cover B. In the upper portion of this box is rigidly secured a suspended ice-receptacle, O, two sides` of which are secured to adjacent walls of the chest, while the ends are separated therefrom, leaving the air-passage e upon each end of the beX, for the passage of cold air from the ieereeeptacle into the cooling-chamber D, this arrangement and construction of parts being now in common use, and in their use7 should the cover be left open for any length of time accidentally, the circulation of air between the cooling-chamber and the ice-receptacle continues, the warm air forcing the cold air out until the temperature within the coolingchamber has been very greatly changed tothe detriment ofthe articles contained in it. To overcome this objection in this style and class of refrigerators, we pivotally secure to the inner walls of the box at each end a fall-leaf, E, the free edge of each of which is connected by means of rods b c t the cover in such manner that as the cover B is raised the leaf or cut-off E will likewise be radially raised into the position shown in Figs. 2 and 3, thereby cutting off all communication through the airpassage between the ice-receptaele and the cooling-chamber, and it has been found in actual test that a refrigerator provided with this device may be left open for a succession of hours without materially changing the temperature in the cooling-chamber. Vhen the cover is closed, the leaves falling down alongside the inner walls of the box, the connecting-rods b c assume the positions shown in Fig. l, thereby again opening the communication through the air-passage between the ice-receptacle and the cooling-chamber.

Vhat we claim as our invention is l. In a refrigerator, the combination, with the suspended ice-receptacle C, of the pivoted dampers E, upwardly-opening cover B, and the rods I) c, connecting said dampers with the cover, whereby the openingI ofthe cover closes the passage between the ice-receptacle and the sides of the refrigerator, substantially as and for the purpose specified.

2. In a refrigerator provided with a suspended ice-receptacle, a cover opening upward, and a radially-swinging leaf or leaves for closing the air-passages between the ice-receptacle and the refrigerating-boX,hung upon rods attached to the cover,whereby the weight of the cover opens the passage between the ice-receptacle and the sides of the refrigerator, substantially as specified.
